Title: Air ring and method for controlling blown film thickness
Inventor: SMITH DAVID J
IPC: B29C48/92
Filed: 1992-02-26
Abstract: Apparatus and method are described for controlling thickness of plastic films produced by the blown film process. The apparatus is an air cooling ring modified to include devices for locally modifying the temperature of the air discharged from the air ring onto the blown bubble. Local variations in the temperature of the cooling air applied to the surface of the bubble result in variations in the bubble cooling rate and viscosity, with consequent variations in thinning during transverse bubble expansion. The method comprises centrally the location and extent of local temperature variation applied to the bubble in response to comparison of measured film thickness with a desired film thickness.

Inventor: BRANDT BERND A
IPC: B66F11/04
Filed: 1992-05-27
Abstract: Abstract A jib assembly is disclosed, for use with an articulated boom carried by an aerial device, having a compact configuration of components which allows a high degree of freedom in the rotation of the jib in the vertical plane and reduced obstruction of the rotational adjustment of the bucket carrier on the boom in the horizontal plane, relative to existing arrangements.  A chain and sprocket arrangement driven by a hydraulic motor powers rotation of the jib coaxially with the bucket shaft and, where a winch is used, with the axis of rotation of the winch.  The arrangement simplifies the routing of hydraulic hoses and affords a more compact and less cluttered arrangement of components at the tip of the boom, which has safety advantages in the environment of a tight distribution of power lines, where distances between live and grounded apparatus are small.

A coin management method is also taught which utilizes the coin management devices, and includes the step of rocking and jiggling the tubular device to align coins into a column of a given denomination. Steps of placing coins of selected value columnarly aligned into the tray channel and arranging them in special bankers rolls by laying an open blank over the coins in the channel and tightly squeezing the ends of the blank over the outside end columnarly arranged coins and lifting the column of coins from the channel, whereupon the blank is closed to form a bankers roll. The method also includes steps of tucking an empty coin sleeve for accommodating a roll of coins of selected value and denomination into one  end of the tube and inserting coins of corresponding denomination and value into the opposed tube end and then elevating the tube and containing the coins above the opposed tube end so that the coins slide into the sleeve, whereupon the coin filled sleeve is removed from the tubular device and closed.

Title: Tartshell maker
Inventor: BOOY ROBERT
IPC: A21C9/00
Filed: 1993-10-20
Abstract: A method of manufacturing tart shells uses a manually operated hinged die and press arrangement in which the die is shaped with a female receptacle for receiving a foil tart case and the press has a male portion for compressing dough into the tart case and squeezing the dough to form a continuous constant thickness layer across the inside of the tart case. To prevent adhesion of the mate portion in the dough, a sheet of plastic film is placed over the tart shell and the dough bail when inserted into the case. The plastic film prevents adhesion of the dough to the male portion and the plastic film can be readily removed after the compression is complete.
